Q: How can I get rid of a bump inside my lip?

A bump inside the lip is most commonly a **mucocele**, a harmless, fluid-filled cyst that forms when a minor salivary gland becomes blocked or damaged. Mucoceles are painless, soft, and often bluish or clear in appearance. While many resolve on their own, a doctor or dentist can help you weigh treatment options, which may include drainage, laser therapy, or minor surgical removal. Other possible causes of a lip bump include canker sores, fibromas, cold sores, or, less commonly, infections or oral cancer. Because the appearance of these conditions can overlap, identifying the exact cause on your own can be difficult. If you're unsure what's causing your lip bump or how urgent it is, the fastest way to get clarity is to take a free, instant, online symptom check . It only takes a few minutes, requires no signup, and can help you understand possible causes and recommended next steps—so you can decide with confidence whether to monitor at home or see a professional.

Explanation

A mucocele is a small, soft bump that may form inside your lip when saliva leaks into nearby tissues. These bumps often happen after a small injury to the lip, like accidentally biting it. Many times, the bump goes away on its own over time.

However, when the bump is irritating or keeps coming back, a health professional may decide to remove it. Removal can be done using surgical procedures, laser treatment, or other methods.

Avoid trying to remove the bump by yourself because you may worsen irritation or cause infection.
